CONVEBTLIBLE STOCK CAR.

Application filed January 30, 1922. Serial 1310. 532,735.

To all whom it may concern Be it known that I, ARoYLn CAMPBELL,

citizen of the United States, residing at Chicago, in the county oi Cookand State ot lllinois, have invented a certain new and use tulImprovement in Convertible Stock Cars, of which the following is a full,clear, concise, and exact description, reference being had to theaccompanying drawings, torming a part of this specification,

This invention relates to improvements in. convertible stock car.

One object of the invention is to provide a stock car which may bereadily converted for the carrying of coal or modities in bulk withoutdanger of loss of the load due to leakage, tothe end that the car willproduce greater revenue for the railroad company. I

Other objects of the invention will more clearly appear "from thedescription and claims hereinafter following.

In the drawings forming a part oit this specification, Figure 1 is aside elevational view of approximately one hall of a convertible stockcar showing my improvements in connection therewith, the upper portionsof the car being omitted. Figure 2 is a hor zontal, sectional View of acar embodying my improvements, part of the floor doors being shown intheir horizontal position and part in, their vertical position as thesame would be employed when theear iscarrying coal or other commoditiesin bulk. Figure 3 is a vertical, longitudinal, sectional view taken atthe center of the car and looking to one side thereof and showing theposition assumed by certainof the parts when the car is employed forcarrying coal or like bulk commodities. Figure lis an enlarged, verticaltransverse, sectional view oi? the car corresponding substantially tothe section line 4-4l of Figure l, Figurefi is a side, verticalsectional view corresponding tozthe section line 5-5 of Figure 3 butupon somewhat larger scale. And Figure 6 is a detail, sectional viewcorresponding to the section line 66 of Figure 3.

The improved stock car, as shown, is provided with center sills 10,bolsters 11, needle beams 12-12, side sills 13, reinforced end wallslet, and fixed floor sections 15 at each end of the car and preferablyextending to points between the trucks.

Intermediate'the fired floor sections 1o,

other like comthe bottom or the car is designed for dumping purposes andto this end, the floor is completed by three floor doors on each side ofthe center sill, the same comprising two end relatively] short floordoors Ari-A and a middle relatively long floor door B, the latterextending across the usual side door opening of the car. As clearlyshown in Figure 1, each of the iioor doors is pivoted. along its outeredge on a level with the fixed floor of the car as by means of T-headedpivot-forming bolts 16 and slotted hinge straps 17 so that the floordoors are adapted to assume either the horizontal position shown in fulllines in Figure at or the dotted line vertical position shown in thesame figure. When in horizontal position, the

floor doors are supported along their free edges by a coverplate 18secured to the tops of the center sills, Each floor door preferablyconslsts of a plurality of transversely extending planks with suitablebinding strips along their pivoted and tree ed esand angle braces 19secured to the under sides as shown in. Figures 2 and, at.

The car sides are formed by a series of horizontally and longitudinallyextending slats 20 -20 secured to and braced by suit able posts 21 anddiagonal braces 22 on their outer sides. The slats 20 are left withspaces indicated at 23-23 therebetween of preferably 2 1 in order toprovide ample space for the circulation of air for the stock transportedin the car.

i I have shown a simple means for holding the floor doors A anclB intheir vertical position, said means comprising loops 24; carried by thedoors and so located that,

when the doors are in vertical position, the loops may be pulledoutwardly through the corresponding space 23 and pivoted latches 25entered within the loops onthe outer side of the slats, the latchesbeing pivoted to the slats, as best indicated in Figures 1 and 4. Whenthe floor doors'are in their horizontal position, the loops 24;dropdown- Wardly so as to avoid presenting any obstruction, the floordoors being suiiiciently by means ot suitable hinge butts 26, the outerfree edges of the drop doors being sustained by a suitable dooroperating mechanism, best shown in Figure ll. For each side oi: the car,the door operating mechanism comprises a longitudinally extending shaft27 and two sets of linkages 23 for each door, each set of linkagesterminating in an elongated llnk 29 slidably mounted within a suitablehouse ing 30 secured to the under side of the door. Anti-frictionrollers 31 are preferably employed on each link 29 as shown in Figure4:. The housings 30 are preferably extended the full width of the doorto brace the latter and also provide a means for attaching the doorhinge strap.

From the preceding description, it will be seen that, when the floordoors A and B are in their vertical position as shown by dotted lines inFigure t, the spaces between the slots of the car side are coveredbetween the fixed floor sections of the car, thereby adapting the carfor the carrying of coal or other bulk commodities without danger ofleakage through the side walls ofthe car where covered by the said'fioordoors.

To close the spaces between the slats of the car side walls opposite thefixed floor.

sections 15 of the car, I employ the following arrangement. On each sideof the car, 0pposite each fixed floor section 15, I employ preferablytwo lattice doors each designated generally by the reference characterD. The lattice doors D are arranged one above the other as clearly shownin Figures 3 and 4-. Each of said lattice doors l) preferably comprisesthree longitudinally and horizontally extending bars 32 held together inproper spaced relation by four hinge straps or plates 33 and diagonalbraces ,orbattens As shown in Figures l and 5, the bars 32 are of su ohsize and so located that, when the lattice doors D arein their dependingvertical posie tion, the bars 32 will. register with and fill threecorresponding spaces 23 between slats of the car side wall, therebyeffectively seal- .ing the car side "and adapting these portions thereoffor carrying coal or other bulk commodities without danger of leakage.The hing'e'straps or plates 33 are pivotally connected at their upperends to suitable hinge brackets 35-35 carried by the correspond-ingslats of the car side wall, the pivotalaxis'of each lattice door'beingso located that, when the door is swung upwardly above the hinge point,as shown in Figure 4:, the bars 32 will overlie the slate of the carside wall without narrowing the spaces between; the slats. It will alsobe noted that thebars 32 of the lattice'doors-lie directly against theslats of the car side and hence are-adaptedto strengthen the latteragainst outwardbending-and in fact, serve *as rump rails for cattle ofdifierent height, will be understood by-those; skilledfinytlie art.

\Vith this arrangement I am enabled to leave wide spaces between theslats necessary for circulation of air for the cattle and at the sametime adapt the car for carrying coal or other bulk comn'iodities withoutdanger of leakage.

As hereinbetore mentioned. the bars 32 of the lattice doors, which barsare preferably of wood, lie directly against the slate of the car sides.It is also desirable that the hinge plates and diagonal braces as alsolie directly against the slats so as to further brace the latter againstoutward pressure. To this end, the bars 32 are notched as indicated bestin Figure 6 at 36, to receive the hinge plates 33 flush therewithin. Thehinge plates 36 are of channel cross section, as shown in, Figure 6,with the flanges of the channel facing toward the interior of the carwhen the lattice doors are in their lower positions as shown. in Figure3. .On theback side of the web of each channel hinge plate 33 where thelatter passes the bars 32, are provided shallow flanges or shoulders 37at right angles to the flanges of the channel hinge strap, saidshallowflaiiges or shoulders 37 being received in corresponding rabbetsof the bars 32 so as to minimize any danger of the bars 32 shiftinglongitudinally of the car, that is, transversely of the hinge straps.The bars 32 are also suitably notched to accommodate the diagonal braces35 flush therewithin so that both the braces and hinge straps and alsothe bars 32 will bear against the slats of the car side when the latticedoors D are in their uppermost positions,

I have shown two lattice doors for each section of the sidewall of thecar since they are more easilymanipulated in small units but obviously asingle lattice door might be employed in lieu of each pair, withoutdeparting from the spirit of the invention.

I have herein shown and described what I now consider the preferredmanner of carrying out the invention, but the same is merelyillustrative and I contemplate all changes and modifications that come,Within the scope of the claims appended hereto.

I claim:
